Easier Commenting of Code in Epsilon 10

Epsilon makes it easier to write and maintain the comments in your
code. We extended the functionality of fill-paragraph to
work with comments. So now you can type Alt-Q to rearrange the line
breaks in your comments to make them pretty. The command in C mode
analyzes the comment to determine the comment style, and maintains it
during comment filling, even if the number of lines changes.

If you provide a numeric prefix argument to Alt-Q, say by typing
Alt-2 Alt-Q, it rejustifies using the current column as the right
margin.

Similarly, auto-fill mode works within comments, and is enabled by
default.
See Commenting Commands for details.
